Abstract: 677,864. Radio direction finding. STANDARD TELEPHONES & CABLES, Ltd. Aug. 11, 1950 [Dec. 1, 1949], No. 19999/50. Class 40 (vii). A radio direction finder comprises a directive antenna system coupled to a receiver, means for varying the antenna system directivity and an indicator including a source of light energized only in response to a predetermined output from said receiver, a pair of opaque discs disposed adjacent to and one over the other with respect to the light source, the first disc being fixed and having a light-passing error-correction pattern thereon and the second rotated in synchronism with said varying means and having a light passing slit system whereby light from the source is modified by the relative positioning of slit system and the source, and a calibrated scale associated with the first disc. A directional antenna such as loop 1 and sense antenna 3 are connected to direction finding receiver 2 giving maximum output voltage at the instant of bearing indication. The loop is rotated by motor 5 which also rotates disc 6 in synchronism by means of shaft 4. The output of the receiver 2 is fed to a circular neon tube 8 which is flashed thereby once per revolution of the aerial and disc. The light from the tube passes through slots 9 and 10 in the disc arranged in angular relation to a radius thereof, as shown. In front of the rotating disc is a fixed mask 11 of transparent material covered with an opaque coating. This coating is removed to provide two channels 14 and 15, each channel forming a continuous correction curve and in co-operation with the slots 9 and 10 providing a corrected bearing indication over the whole 360 degree field. A bearing scale 16 is provided fixed to the frame 12 of mask 11.

Title: Improvements relating to sterilizers
IPC: A61L2/07
Filed: 1951-08-24
Abstract: 703,871. Sterilizing autoclave; steam cooking. EVERETT & CO., Ltd., S. & R. J., SALT, F., and TILLETT, L. A. Aug. 19, 1952 [Aug. 24, 1951], No. 20004/51. Classes 28(1) and 81(1) In a portable sterilizing unit (said to be applicable in pressure cooking) having a closed steam circuit comprising an autoclave cylinder which is in continual communication with a boiler so that steam generated in the boiler enters the autoclave and steam condensed in the autoclave runs back into the boiler, cool water may be circulated through pipes in the autoclave and boiler, in order to enable steam in the autoclave to be condensed rapidly when sterilization ends. In the embodiment shown in Figs. 3, 4 and 5, the cooling water system comprises a pressure relief tank 16 connected to an injector chamber 12 in which an injector 11 is arranged to draw water from the injector chamber into the cooling pipe 14 by means of steam from an electricallyheated boiler 3. In operation steam generated in the boiler 3 passes to the autoclave 1 and drives the air out of the autoclave through air valves 22 which are closed by means of a thermally-operated mechanism when steam reaches them. The required pressure in the autoclave is controlled by an adjustable pressure operated switch 6, Fig. 3. Any steam condensed in the autoclave trickles back down a steam pipe 8 into the boiler. When sterilization is complete the current is switched off and a steam valve 10 opened. The pressure in the autoclave and boiler forces hot water and steam through the injector 11, cool water from the injector chamber is drawn in, and the comparatively cool mixture is forced through the tube 14 and then into the pressure relief cylinder 16. The water in the injector cylinder is continually made up from the pressure relief cylinder through a pipe 28, Fig. 3. The normal water level in the pressure relief cylinder is sufficient to maintain the water level in the boiler and injector chamber nearly at the top when the system is cool and the steam valve 10 is open. The water level is indicated by a glass gauge 17, Fig. 4, the upper end of which is connected to the upper part of the pressure relief cylinder and the lower end of which is connected to the bottom of the injector chamber. Pressure between the top of the injector chamber and the top of the pressure relief cylinder is balanced by a pipe 20. The valves 22 are connected through pipes 23, Fig. 3, to the pressure relief cylinder which is provided with a vent tube, to which the upper end of the gauge is connected, and which leads to a vent opening 25. A safety valve 26 is provided on the autoclave which may be set to blow off through the vent 25 at any desired pressure. A further safety precaution is the provision of a fusible plug 27 on the boiler which melts and vents the system if the temperature gets too high.

Title: Auxiliary steering gear for aircraft
IPC: B64C13/00
Filed: 1920-07-09
Abstract: 148,236. Flettner, A. Sept.. 3, 1917, [Convention date]. Steering and balancing.-Relates to auxiliary planes for effecting the adjustment of the steering- planes of aircraft, in which the auxiliary plane is automatically turned back so as to be gradually put out of operation as the steering-plane reaches the desired deflexion. The Figure shows a balancing-plane m for the wing-flaps provided with arms b carrying an auxiliary plane i, which may also be fitted with arms h carrying a second auxiliary plane g. A lever a, mounted on the pivot of the arms b, is actuated by the pilot, and engages by means of a toothed sector with another sector on a lever c, which is mounted on the arm b and connected by a rod to an arm d loose on the axis of the plane i, another rod connecting t.he arm d to a second arm f rigid with the plane g. Operation of the lever a by the pilot adjusts the plane g, the air pressure on which moves the plane i, which is then also acted on by the air to effect the adjustment of the plane m and the, flaps. As the arms b move, the teeth of the lever c, by engagement with the then fixed lever a, produce a backward movement of the lever c and plane g. The second auxiliary plane may be dispensed with. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following subject-matter. The toothed sectors may be replaced by a bell-crank having one arm connected to the lever a and the other arm to the auxiliary plane, or by pulley and cable gearing. Fig. 6 (Cancelled) shows an arrangement of cables and pulleys or levers for actuating the auxiliary plane. Fig. 8 (Cancelled) shows the control wires for the auxiliary plane led through the axis of the steering-plane. A brake arrangement is described whereby the arm carrying the auxiliary plane is held fast as soon as the desired adjustment has been attained. Fig. 10 (Cancelled) shows the auxiliary plane a arranged to be moved to and fro upon the lever arm b. The auxiliary plane may be arranged at right-angles to the air-stream, and may be kept so by means of parallel link-work. The effect of the movement of the centre of pressure of a steering-plane may be counteracted by means of a small plane carried by arms rigid with the steering-plane and extending in front thereof. Fig. 14 (Cancelled) shows an auxiliary plane a which slides as it is tilted, so as to maintain the centre of pressure over its pivot. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 27956/10.
Patent GB-408124-A (GB)
Title: Improvements in and apparatus for operating internal combustion engines
IPC: F02M1/00
Filed: 1933-07-18
Abstract: <PICT:0408124/III/1> Fuels for internal-combustion engines consist of readily depolymerized liquid to solid polymers; they are used as required by heating to depolymerize, and supplying the split products to the combustion chamber.  Specified fuels having m.w. from under 400 to 5000 are hydro-rubber, polymers of isobutylene or of styrene, and oxygen-containing polymers, e.g. aldols, e.g. of isobutyraldehyde and diacetone alcohol.  The depolymerization is preferably effected by the heat of the exhaust gases, but the decomposition chamber may be heated electrically, by treating cartridges, or by burning benzine or petroleum.  The depolymerization may be assisted by catalysts added to the polymers or introduced into or applied to the inner surface of the decomposition chamber.  Catalysts specified are phosphoric acid and soda lime on pumice stone.  The engine is started by special means, e.g. an auxiliary fuel such as benzine or petrol. For example, the engine E is started on petrol passed through a vaporizer 4, and the exhaust gases are used to heat the decomposition chamber 3 to about 350 DEG  C. and the fuel tank 1 to about 100 DEG C.  When the isobutylene polymer of m.w. about 5000 contained in the tank 1 has become mobile, it is fed by a dosing pump 2 to the chamber 3, from which isobutylene and its lower polymers are drawn to the engine.  The petrol is then cut off, and the fuel supply regulated by a valve 5 coupled with a throttle flap 6.  Alternatively, the tank 1 may be heated by used cooling water.ALSO:Liquid and solid polymers of isobutylene, styrene, acetone and isobutyraldehyde of m.w. under 400--5000 are split and used as required as fuel for internal-combustion engines.  The polymers of isobutylene may be obtained by treating isobutylene with dilute sulphuric acid, alkaline bleaching earths, and especially volatile inorganic halogen compounds, preferably at 50 DEG  C.--minus 80 DEG  C. For example, boron fluoride may be used cold, dilute sulphuric acid at 50--100 DEG C.  Tri-isobutylene, B.P. 175 DEG  C., may be obtained by passing isobutylene through a tower against 70 per cent sulphuric acid trickling over Raschig rings or glass pearls at atmospheric temperature, allowing the product to stand to separate as an upper layer triisobutylene containing di-isobutylene and warming the sulphuric acid ester layer to decompose the ester and separate further tri-isobutylene; the di-isobutylene is removed from the tripolymer by distillation. Polymers of styrene may be obtained by protracted heating to above 300 DEG  C.
